Abstract

A golf club head with a hosel hole cover that helps improve the performance of the golf club head is disclosed. More specifically, the present invention relates to a golf club head having a hosel hole cover at a bottom portion of an interchangeable connection system that not only provides improved performance of the golf club head by strategically utilizing an existing opening to adjust the weighting of a golf club head, but it also improves the aerodynamics of the golf club head by eliminating undesirable recesses that could be detrimental to the aerodynamics of a golf club head.

Claims (39)

1 . A golf club head comprising:

a body portion further comprising a crown portion, a sole portion, a heel portion, and a toe portion;

a hosel region located near a heel portion of said golf club head, said hosel region further comprising;

an upper end having a releasable hosel mechanism;

a lower end having a hosel hole, said hosel hole further comprising;

a one or more non-threaded recessed undercuts along a side wall of said hosel hole,

a hosel hole cover, adapted to substantially cover an entirety of an internal surface of said hosel hole, and

a retention mechanism, adapted to secure said hosel hole cover to said golf club head, wherein said retention mechanism comprises one or more non-threaded protrusions,

wherein said one or more non-threaded protrusions are adapted to engage said one or more non-threaded recessed undercuts to secure said hosel hole cover to said golf club head,

wherein at least a portion of said hosel hole cover is deformable, and

wherein said hosel hole cover bends to allow access to said hosel hole by disengaging at least one of said one or more non-threaded protrusions from said one or more non-threaded recessed undercuts.

2 . The golf club head of claim 1 , wherein said bending of said hosel hole cover maintains the engagement of at least one of said one or more non-threaded protrusions with at least one of said one or more non-threaded recessed undercuts.

3 . The golf club head of claim 2 , wherein said hosel hole cover further comprises a receptacle adapted to receive a tool, wherein said tool facilitates the bending of said hosel hole cover.

4 . The golf club head of claim 2 , wherein said hosel hole cover further comprises;

a base piece made out of a non-deformable rigid material, and

a cover piece made out of a deformable polymeric material.

5 . The golf club head of claim 4 , wherein said bending of said hosel hole cover is isolated within said cover piece of said hosel hole cover.

6 . The golf club head of claim 5 , wherein said hosel hole cover further comprises a receptacle opening, adapted to receive said retention mechanism,

said receptacle opening has a surface area of between about 55 mm 2 to about 300 mm 2 .

7 . The golf club head of claim 6 , wherein said surface area of said receptacle opening has an area of between about 65 mm 2 to about 200 mm 2 .

8 . The golf club head of claim 7 , wherein said surface area of said receptacle opening has an area of about 90 mm 2 .

9 . A golf club head comprising:

a body portion further comprising a crown portion, a sole portion, a heel portion, and a toe portion;

a hosel region located near a heel portion of said golf club head, said hosel region further comprising;

an upper end having a releasable hosel mechanism;

a lower end having a hosel hole, said hosel hole further comprising;

a one or more non-threaded recessed undercuts along a side wall of said hosel hole,

a hosel hole cover, adapted to substantially cover an entirety of an internal surface of said hosel hole, and

a retention mechanism, adapted to secure said hosel hole cover to said golf club head, wherein said retention mechanism comprises one or more non-threaded protrusions,

wherein said one or more non-threaded protrusions are adapted to engage said one or more non-threaded recessed undercuts to secure said hosel hole cover to said golf club head,

wherein at least a portion of said hosel hole cover is deformable, and

wherein said hosel hole cover bends to allow access to said hosel hole by disengaging at least one of said one or more non-threaded protrusions from said one or more non-threaded recessed undercuts,

wherein said hosel hole cover further comprises a receptacle opening, adapted to receive said retention mechanism,

said receptacle opening has a surface area of between about 55 mm 2 to about 300 mm 2 .

10 . The golf club head of claim 9 , wherein said surface area of said receptacle opening has an area of between about 65 mm 2 to about 200 mm 2 .

11 . The golf club head of claim 10 , wherein said surface area of said receptacle opening has an area of about 90 mm 2 .

12 . The golf club head of claim 9 , wherein said bending of said hosel hole cover maintains the engagement of at least one of said one or more non-threaded protrusions with at least one of said one or more non-threaded recessed undercuts.

13 . The golf club head of claim 12 , wherein said at least one or more non-threaded protrusions that is disengaged from said at least one or more non-threaded recessed undercut and said at least one or more non-threaded protrusion that remains engaged from said at least one or more non-threaded recessed undercut are located at opposite ends of said hosel hole cover.

14 . The golf club head of claim 13 , wherein a number of said at least one or more non-threaded protrusions that is disengaged from said one or more non-threaded recessed undercuts is lower than said at least one or more non-threaded protrusions that remains engaged from said one or more non-threaded recessed undercuts when said hosel hole cover is bent away to allow access to said hosel hole.
